-----Invalid parameter number: parameter was not defined ----
SELECT id WHERE x = ?, y = ?, z = ?
Might produce the Log: Invalid parameter number: parameter was not defined with params ("x","y","z")
This looks like it shouldn't be throwing an error, but if the indexes are something like:
0 => x, 1 => y, 4 => z
解决： array_values($arr); //重新排列一下数组的key,变成有序
